Hydraulic System
When you cycle the machine controls, the machine can move suddenly. Contact between the machine and external objects or ground personnel can result in serious injury or death. Before you cycle the machine controls, the machine should be located in an unobstructed, hazard-free work area that is away from external objects and ground personnel.
Make sure that the area is clear of personnel and equipment.Note: The hydraulic lockout control must be in the UNLOCKED position before the hydraulic controls will function.
Allow the engine to warm up at low idle for at least 5 minutes. Engage the work tool controls and disengage the work tool controls. This will speed up the warm-up of the hydraulic components.When you idle the machine for warm-up, observe the following recommendations:
If the temperature is greater than 0°C (32°F), warm up the engine for approximately 15 minutes.
If the temperature is less than 0°C (32°F), warm up the engine for approximately 30 minutes.
If the temperature is less than − 18°C (0°F) or if hydraulic functions are sluggish, additional time may be required.
The hydraulic oil temperature should be higher than 25 °C (77 °F) before performing work with the machine. Make sure that the warm-up procedure is performed.If the hydraulic oil temperature is less than 25 °C (77 °F) and the machine is operated abruptly, serious damage to the hydraulic components may occur.
Note: The recommended operating temperature of the hydraulic fluid for this machine is 55 °C (131 °F).
To warm up the hydraulic oil, turn the engine speed dial to the medium engine speed. Run the engine for approximately 5 minutes and move the joystick intermittently from the BUCKET DUMP position to the HOLD position. Do not hold the joystick in the BUCKET DUMP position with the bucket cylinder fully extended for more than 10 seconds.This allows the oil to attain relief pressure, which causes the oil to warm up more rapidly.Note: If the joysticks are held for more than 30 seconds, the machine ECM will go into a "Warm-Up Mode Power Derate" setting. "Warm-Up Mode Power Derate" will be shown on the monitor screen. When "Warm-Up Mode Power Derate" is active, the machine ECM limits the hydraulic pump torque to 50 percent. Release the joysticks in order to cancel the "Warm-Up Mode Power Derate" setting.
Turn the engine speed dial to the maximum engine speed and repeat step 3.
Cycle all controls in order to circulate warm oil through all hydraulic cylinders and all hydraulic lines, and through the swing motor and travel motors.
Observe the gauges and the indicators frequently during the operation.
Turbo Protection Power Derate - After an engine start, the engine speed will be set to dial one position and the hydraulic power limited for a time period . During this period, the monitor displays the message "Warm -Up Mode Power Derate". (Maximum is around 30 seconds). After the turbo bearing lubrication is sufficient, the engine speed goes to the setting dial speed and the monitor stops to display the message.Hydraulic System Automatic Warm-up
